121"x15", 2.52 pitch.  Internal drive.  Most newer tracks will fit, but the newer tracks have extra internal drive lugs, so the idler wheels on the skid and drive axle would need to be spaced to clear them. 

If you're looking for a stock replacement, I have a few real nice tracks off from Invaders that I would sell for relatively cheap.

Thanks for your help I have a local guy that has a 121 with 1 inch lugs on it I am going to see if this will work. Not many groomed trails around here and need the longer lugs.

I put a 1" camoplast hacksaw track on my 81 440 Invader, by far the BEST mod I have done.  Well worth the extra effort!  Good luck!

I think the 1" lugs will hit the tunnel up front. Can't say for sure but I think I heard that you should stay around .75

I've got almost 1,000 miles on the 1" track with no issues.

I have a parts sled that I was going to take the skid out of to rebuild for my good sled. I can get a 1" track for cheap money, but it is picked out. Are picks a bad idea on a 1" track?

Make sure the studs aren't too long.  You will need tunnel protectors .
